Abstract
(EN)
A touch detecting assembly, a touch sensitive device, and a portable electronic apparatus are provided. The touch detecting assembly (100) comprises: a substrate (1); and a plurality of induction units (2) disposed on the substrate (1) and not intersecting with each other, each induction unit (2) comprising an induction body (20), and a first electrode (21) and a second electrode (22) connected with the induction body (20) respectively. Each induction body (20) has a rectangular shape with a plurality of empty parts (24), the plurality of empty parts (24) are arranged in a predetermined pattern to define a current passage (25) which extends between a first end and a second end of the induction body (20), and a cross-sectional area of the current passage (25) in a plane orthogonal to an extending direction of the current passage (25) is smaller than that of the induction body (25) in the plane.

La présente invention concerne un ensemble de détection tactile, un dispositif tactile et un appareil électronique portable. L'ensemble de détection tactile (100) comprend : un substrat (1) ; et une pluralité d'unités d'induction (2) disposées sur le substrat (1) et ne formant aucune intersection entre elles. Chaque unité d'induction (2) comprend un corps d'induction (20) ainsi que des première (21) et seconde (22) électrodes respectivement connectées au corps d'induction (20). Chaque corps d'induction (20) a une forme rectangulaire comportant une pluralité de parties vides (24) agencées selon un modèle préétabli de façon à définir un passage de courant (25) qui s'étend entre les première et seconde extrémités du corps d'induction (20). Une zone en coupe transversale du passage de courant (25) dans un plan orthogonal à la direction d'extension du passage de courant (25) est plus petite que celle du corps d'induction (20) dans le plan.
